Under the capitalistic regimes, early adopters are doing great service to the society by spending money. It's sort of a sacrifice and indirect altruism, as a matter of fact. I'll be probably awaiting the release of GTX 1060 by the likes of ASUS and MSI though I'm unsure of my patience, which I suppose is the hardest part. The rumor has it that GTX 1060 will be released no earlier than September 2016. On the other hand, excessive patience is not always helpful in this mortal and ephemeral life.
It looks like GTX 1060 would perform similar to GTX 970, which has been incredibly satisactory to me so far in terms of graphics prowess.
I'd expect the 1050 series to be the ones that forgo the PEG connector.
GTX 1080: Pretty awesome idle and 2D power draw....especially with 8GB of VRAM.
GTX 1070: Due out on June 10 and spec's are leaking.
5W higher TDP than the GTX 970...but it also has 8GB VRAM vs 4GB on the '970. I think this'll be the part to watch for "moderately" priced 2160p gaming. Intro price is high, but if AMD gets it's act together, the high end Polaris will compete against this part. So, street price will probably drop to $350..maybe less...it'll be interesting to watch how badly vendors rape the early adopters of both the 1070 and 1080.
